Definitions
- the present invention concerns a machine for treating objects, in particular a so-called "tunnel” treatment machine, in which successive steps of the treatment of objects can be carried out in one or more treatment chambers in which relative treatment zones are disposed one after the other.
- treatment it is possible to understand “in their entirety”, both pretreatment operations of the objects, such as pre-washing, with hot or cold water and/or with detergents or other chemical products, and also washing operations proper, and also drying operations. Also included in the same term “treatment” are thermal disinfection, sterilization, generally in an autoclave, and decontamination by means of particularly aggressive and dangerous decontaminating substances, detergents and/or chemical agents, such as for example peracetic acid.
- the objects that can be treated in the treatment machine in question can be instruments used in the health sector, in the laboratory, for analysis or for research, instruments used in the pharmaceutical sector, or instruments in the medical sector, surgical instruments or comparable or similar instruments, without excluding, however, the application of the present invention to the treatment of objects in general.
- At least one door is provided, associated with an entrance aperture, which is mobile and driven by an opening and closing mechanism to assume a high or open position in which it allows the entrance of the objects to be treated in the treatment chamber, and a low or closed position in which, in cooperation with fluidic sealing means, it seals the washing chamber from the outside.
- object-holder containers can also be inserted, located in sequence one after the other in the chamber.
- a rollerway is provided on which the object-holder containers are rested and situated in correspondence with the door of the machine. From the door, therefore, the containers enter with the objects to be treated and the containers with the treated objects come out.
- rollerways In the case of a "pass-through" treatment machine, generally two rollerways are provided, positioned on diametrically opposite sides of the machine, of which one side has an entrance door of the containers with objects to be treated and, the opposite side, has an exit door of the containers with the treated objects.
- the treatment machines configured for sterilization are generally machines with a deep treatment chamber, for example even a few meters long, therefore, in such machines, multiple object-holder containers disposed in sequence are loaded.
- relatively high temperatures are reached, for example up to about 140°C, therefore, it is good practice if the sterilization machine does not have, inside the treatment chamber, automatic movement means for the object-holder containers and/or sensors to detect their position.
- the object-holder containers are thrust and translated one after the other through the loading door of the treatment chamber.
- a first container will be inserted into the chamber, then, once the insertion is completed, a second container will be positioned after the first container, which, following the thrust of the second container, will occupy a bottom zone of the chamber.
- the chamber is closed and the treatment cycle begins.
- the intended cycle is not completed and it becomes necessary to remove the two containers located in the chamber, the loading door is opened so that they can be extracted.
- the second container inserted last and positioned in proximity to the loading door, can be extracted without difficulty, but the first container inserted, which is at the bottom of the chamber, is more difficult to extract.
- Document WO-A-2015/145383 describes a device to introduce and extract containers with respect to a sterilization machine along a direction of feed, comprising a container loading plane defining a movement path, and motorized linear guide members disposed along the container loading plane and configured to move the containers in a guided manner along the movement path in the direction of feed.
- the device also comprises an auxiliary guide extension connected to the container loading plane and mobile between a first retracted position, in which it is comprised in the bulk of the container loading plane, and a second operating position, in which it is at least partly protruding from the container loading plane to define an extension of the movement path.
- the device has undoubted advantages in moving the baskets or containers, in the sense that it prevents possible blockages thereof during moving, it has some limitations with regard to the possibility of automatic attachment of a plurality of containers disposed in sequence, so that the sterilizing machine provided with this device has problems similar to those mentioned above.
- one purpose of the present invention is therefore to provide a machine for treating objects which allows the automatic attachment of several object-holder containers disposed in sequence upon their insertion into the treatment chamber, so that, acting on the slider nearest to the loading door, in the opposite direction to the insertion direction, all the object-holder containers present in the chamber can be extracted, and therefore also the object-holder container located at the bottom of the treatment chamber and in the farthest position from the loading door, thanks to the fact that it is attached to the object-holder container closest to the loading door.
- Another purpose of the present invention is to provide a machine for treating objects which has a device of a mainly mechanical type to automatically attach the sliders upon their insertion.
- Another purpose of the present invention is to provide an effective and automatic reciprocal attachment apparatus for several object-holder containers, which allows to translate the object-holder containers simultaneously at least in a step where they are extracted from the treatment chamber and at least as far as the loading door of any machine for treating objects.
- Another purpose of the present invention is to perfect a quick, automatic and safe method for the reciprocal attachment of several object-holder containers.
- the Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
- a machine for treating objects, in particular washing, thermal disinfection and/or sterilization of objects comprises at least a treatment chamber configured to house a plurality of object-holder containers located in sequence and comprising opposite lateral walls.
- the machine comprises at least a releasable connection device of the object-holder containers, associated with at least one of the object-holder containers and configured to cooperate with activation means positioned on the lateral walls inside the treatment chamber, so that, inserting an object-holder container in the treatment chamber after at least a first object-holder container already inserted in the chamber and moving the object-holder containers toward the inside of the chamber, the releasable connection device is automatically activated by the activation means in order to reciprocally connect the object-holder containers, so as to allow a simultaneous extraction, acting on the last object-holder container inserted.
- the device comprises at least a sliding block associated with at least a first head and/or tail bar of a object-holder container and provided with an attachment element able to engage the first bar and at least a second bar of another object-holder container, following the translation of the sliding block with respect to the first bar, the sliding block is made to translate in one direction or the other with respect to the bar by means of the activation means.
- the machine comprises, on the lateral walls of the chamber, de-activation means of the releasable connection device, so as to automatically separate the object-holder containers during their extraction step from the treatment chamber.
- the de-activation means are positioned in proximity to an entrance aperture of the treatment chamber.
- the releasable connection device is provided both at the tail and at the head of each object-holder container.
- connection device is provided both at the head and at the tail of each object-holder container, the activation means and the de-activation means of the connection devices can be staggered at least in height in the lateral walls inside the treatment chamber.
- the sliding block can comprise at one end at least a first rolling element able to engage with the activation means and, at the other end, at least a second rolling element able to engage with the de-activation means.
- the first and second rolling elements can be alternatively protruding from opposite sides of the object-holder container, in particular longitudinal sides.
- the activation means can comprise at least a cam profile which can engage with the first rolling element of the releasable connection device.
- the de-activation means can comprise at least another cam profile which can engage with the second rolling element of the releasable connection device.
- the invention also concerns a connection device of a plurality of object-holder containers located in sequence in a treatment machine, in particular for washing, thermal disinfection and/or sterilization of objects.
- connection device comprises at least a sliding block associated with at least a first head and/or tail bar of a first object-holder container and provided with an attachment element able to engage the first bar and at least a second bar of a second object-holder container, following a translation of the sliding block with respect to the first bar; the sliding block is made to translate in one direction or the other with respect to the bar by means of activation means positioned in the machine.
- the invention also concerns an object-holder container usable in a machine for treating objects, in particular for washing, thermal disinfection and/or sterilization of objects, which comprises at least one connection device as defined above.
- the invention also concerns a method to connect a plurality of object-holder containers located in sequence in a treatment machine, in particular for washing, thermal disinfection and/or sterilization of objects.
- the method provides: to insert a first object-holder container in a treatment chamber; to insert at least a second object-holder container in the treatment chamber after the first object-holder container has already been inserted in the treatment chamber and to move the object-holder containers toward the inside of the treatment chamber; at least one of the object-holder containers is provided with a releasable connection device automatically activated by activation means disposed on the lateral walls inside the treatment chamber to reciprocally connect said object-holder containers, so as to allow a simultaneous extraction, acting on the last object-holder container inserted.
- the device can comprise at least a sliding block associated with at least a first head and/or tail bar of a object-holder container and provided with an attachment element able to engage the first bar and at least a second bar of another object-holder container following a translation of the sliding block with respect to the first bar; the sliding block is made to translate in one direction or the other with respect to the bar by means of activation means.
- a treatment machine 10 comprises at least one treatment chamber 11 in which a plurality of object-holder containers, disposed in sequence, for example, the object-holder containers 12 and 13 can be positioned.
- the object-holder containers 12 and 13 may be in the form of baskets or suchlike.
- the object-holder containers 12 and 13 comprise a frame 14 provided with at least one head bar 15, see for example the head bar 15 of the object-holder container 13, and at least one tail bar 16, see for example the tail bar 16 of the object-holder container 12.
- the bars 15 or 16 are directed in a direction T substantially transverse with respect to a direction L for the insertion and extraction of the object-holder containers 12 and 13 into and from the chamber 11.
- the frame 14 also comprises at least one pair of sides 20 and 21, substantially directed in the direction L.
- the sides 20 and 21 are preferably made at the same height.
- the sides 20 and 21 are preferably disposed at the same height as the bars 15 and 16, therefore in proximity to the base of the object-holder containers 12 and 13.
- the length of the object-holder container or containers 12 and 13 located in sequence is normally such that the whole length of the treatment chamber 11 is substantially occupied.
- the present invention can also concern a "pass-through" treatment machine, since, in the event of failure, breakdown, error in the cycle or suchlike, as mentioned above, the unloading door is automatically blocked so that, in fact, the loading aperture would also be used to remove the object-holder containers.
- the treatment chamber 11 will be provided inside it with means, not shown in the drawings, useful to carry out a specific treatment of the objects located in the object-holder containers 12 and 13, for example washing, thermal disinfection, sterilization or other means.
- the chamber 11 of the treatment machine 10 since it is an example of a "single door" machine, comprises an aperture 17 for inserting the object-holder containers 12, 13 with the objects to be treated and for extracting the object-holder containers 12, 13 with the treated objects.
- the aperture 17 will be opened or closed by means of a corresponding door, not shown in the drawings, which can be driven manually or automatically.
- the door for opening and closing the aperture 17 can be a sliding door, for example a rolling shutter door or suchlike, and is able to guarantee an adequate seal once the chamber 11 has been closed to carry out the treatment of the objects located in the object-holder containers 12, 13.
- the object-holder containers 12, 13 rest on a pair of supports 18, for example a pair of parallel tracks.
- the object-holder containers 12, 13 can also comprise wheels 19 or suchlike in order to move them inside the chamber 11 in direction L.
- a releasable connection device 22 of the object-holder container 13 is positioned with the object-holder container 12 already inserted in the treatment chamber 11.
- connection device 22 substantially comprises a sliding block 23 resting on one side of the bar 15 and provided with at least one attachment element 24, protruding from the other side of the bar 15, that is, the external side of the object-holder container 13.
- the attachment element 24 can be, for example, shaped like an upside down U and can have an amplitude such as to be able to sit astride at least two adjacent transverse bars of two object-holder containers 12, 13, for example the bars 15 and 16.
- the sliding block 23, see fig. 3 comprises a pair of slits 25, in each of which a pin 26 integral with the bar 15 is inserted.
- the slits 25 allow the sliding block 23 to slide in direction T, in one sense or the other, with respect to the bar 15.
- the amplitude of the slits 25 substantially defines the extent of the transverse travel of the sliding block 23.
- the sliding block 23 also comprises a rolling element on each end, for example a wheel, see for this purpose the wheels 27 and 28.
- the wheels 27 and 28 are idle and able to protrude alternatively from one side or the other of the object-holder container 13 through suitable holes 29 made in the sides 20 and 21, see for example the hole 29 of fig. 1 made in the side 21 and from which the wheel 28 can exit, as we shall see.
- the wheel 27 initially protrudes from the object-holder container 13, while the wheel 28 is housed inside the object-holder container 13.
- the height at which the wheels 27 and 28 are positioned is different, for example, in the drawings shown, the wheel 27 is situated at a height greater than the wheel 28.
- the treatment chamber 11 comprises two opposite lateral walls 30 and 31, on which activation means of the connection device 22 are positioned, for example a cam profile 32 suitably protruding toward the inside of the chamber 11.
- the cam profile 32 is positioned at a height such as to cooperate with the wheel 27 protruding from the object-holder container 13, when the object-holder container 13 is inserted in direction L.
- the wheel 27 will be retracted inside the object-holder container 13, determining, as we will see, a transverse activation displacement of the connection device 22 and, in particular, a translation of the sliding block 23 and of the corresponding attachment element 24.
- connection device 22 On the lateral wall 31 of the treatment chamber 11 opposite the lateral wall 30, means are positioned to de-activate the connection device 22, for example a cam profile 32', which can be used in the extraction step of the object-holder container.
- the cam profile 32' also protrudes appropriately toward the inside of the chamber 11.
- the cam profile 32' that de-activates the connection device 22, and therefore reciprocally separates the object-holder container 12 and the object-holder container 13, is positioned in proximity to the entrance aperture 17 of the chamber 11, so as to take the object-holder container 12, which is more remote and housed more internally in the chamber 11, toward the exit of the chamber 11, hence in an easily grippable position.
- the cam profile 32' is positioned at a height such as to cooperate with the wheel 28, which will protrude from the object-holder container 13 when the object-holder container 13 is removed from the chamber 11.
- the wheel 28 will again be retracted inside the object-holder container 13, determining, as we shall see, a transverse de-activation displacement of the connection device 22 and, in particular, a translation of the sliding block 23 and of the corresponding attachment element 24.
- the activation cam profile 32 therefore, in this example, is situated at a greater height than the de-activation cam profile 32', but it could also be the other way round.
- connection device 22' is positioned in the tail bar 16 of the object-holder container already inserted in the treatment chamber 11.
- connection devices 22 and 22' at both the head and tail of the object-holder containers 12 and 13 also allows the operator not to confuse the head part with the tail part of the object-holder container 12 or 13, since the head and tail parts will be reciprocally symmetrical.
- connection device 22' is very similar to the connection device 22 associated with the bar 15 of the object-holder container 13.
- connection devices 22 and 22' When the connection of the object-holder containers 12 and 13 is complete, preferably, the attachment elements 24 and 24' of the connection devices 22 and 22' will be disposed in specular positions with respect to the longitudinal axis L.
- connection device 22' will therefore be provided with a sliding block 23', at the ends of which corresponding wheels 27' and 28' are positioned.
- connection device 22' which in this example is situated at a greater height than the wheel 28', is therefore able to cooperate with a cam profile 33 to activate the connection device 22'.
- the cam profile 33 suitably protrudes toward the inside of the chamber 11.
- the cam profile 33 is positioned on the lateral wall 31 of the treatment chamber 11 in a longitudinally staggered position with respect to the position of the cam profile 32', so as to allow the alternate drive of the wheels 27' of the object-holder container 12 and of the wheel 28 of the object-holder container 13.
- connection device 22' is instead able to cooperate with a cam profile 33' to de-activate the connection device 22'.
- the cam profile 33' suitably protrudes toward the inside of the chamber 11.
- the cam profile 33' to de-activate the connection device 22' and thus to separate the object-holder containers 12 and 13 is disposed in proximity to the entrance or exit aperture 17 of the treatment chamber 11.
- the cam profile 33' is positioned on the lateral wall 30 of the treatment chamber 11 in a longitudinally staggered position with respect to the position of the cam profile 32, so as to allow the alternate drive of the wheels 28' of the object-holder container 12 and of the wheel 27 of the object-holder container 13.
- connection device 22 In the same way as seen for the connection device 22, also the sliding block 23' of the connection device 22' is provided with slits 25' able to be engaged by pins 26' integral with the bar 16, in this case the tail bar of the object-holder container 12.
- the activation means of the connection devices 22 and 22' comprising for example the cam profiles 32 and 33
- the de-activation means of the connection devices 22 and 22' are also positioned at the same height and in the same longitudinal position in the chamber 11.
- the activation cam profiles 32 and 33 are longitudinally staggered with respect to the cam profiles 32' and 33'.
- cam profiles 32 and 33 are also situated at a greater height than the cam profiles 32' and 33'.
- connection and disconnection of the object-holder containers 12 and 13 shown schematically in figs. 4a-4d substantially relates to the zone Z circled in dashed lines in fig. 3 .
- the object-holder container 13 for example by means of a rollerway or suchlike, is moved into proximity to the entrance aperture 17 of the treatment chamber 11, as can be seen for example also in figs. 1 or 3 .
- rollerway or other approach and removal unit outside the treatment chamber 11 can be provided with movement means with respect to the chamber 11, for example translation means, so as to be able to discharge the object-holder containers 12 and 13 extracted from the chamber 11.
- the head bar 15 of the object-holder container 13 is provided with at least a groove 34 of an amplitude such as to allow the temporary passage of the attachment element 24' of the connection device 22' associated with the object-holder container 12.
- the tail bar 16 of the object-holder container 12 is also provided with a groove 34' of an amplitude such as to allow the temporary passage of the attachment element 24 of the connection device 22 associated with the object-holder container 13.
- the object-holder container 13 is thrust in direction L1 inside the treatment chamber 11 until the bar 15 and the bar 16 are reciprocally adjacent, see fig. 4b .
- the attachment element 24' is positioned above both the bars 15 and 16 and has crossed the groove 34 of the bar 15.
- the attachment element 24 will have passed the groove 34' of the bar 16 and will find itself above both bars 15 and 16.
- the object-holder container 12 Continuing in the thrust of the object-holder container 13 inside the treatment chamber 11, the object-holder container 12 will move toward the bottom of the chamber 11.
- connection device 22' and the corresponding attachment element 24' are automatically translated in direction T1', that is, in this case, toward the center of the chamber 11.
- the wheel 27' cooperates with the cam profile 33
- the wheel 27 of the connection device 22 cooperates with the cam profile 32, so that the device 22 moves automatically in a direction T1, opposite to the direction T1', thus also toward the center of the chamber 11.
- the wheel 28 of the connection device 22 begins to exit from the hole 29 and to protrude out of the object-holder container 13.
- the translation T1 and T1' of the two connection devices 22 and 22' causes the automatic overlapping of the attachment elements 24 and 24' on both the bars 15 and 16, as shown for example in fig. 4d for the attachment element 24'.
- the attachment elements 24 and 24' will be substantially in a symmetrical position with respect to the longitudinal axis L.
- the object-holder containers 12 and 13 are attached to each other and the first object-holder container 12 can be taken, always thrusting the object-holder container 13, to the bottom of the treatment chamber 11.
- the object-holder container inserted last, hence the object-holder container 13, is translated in the direction L2, see fig. 4d again, and draws with it the first object-holder container inserted in the chamber 11, that is, the object-holder container 12, since they are reciprocally connected.
- the protruding wheel 28 of the connection device 22 does not interact with the activation cam profile 33, in this case it passes under the cam profile 33 and instead interacts with the de-activation cam profile 32, thus determining an automatic translation in direction T2, see fig. 4e , of the connection device 22.
- connection device 22' will cooperate with the cam profile 33' so as to automatically retract and translate the connection device 22' in direction T2', and then return the wheel 27' in a position protruding from the object-holder container 12.
- the translation T2' will preferably be the same entity and opposite to the translation T1', and the translation T2 will preferably be the same entity and opposite to the translation T1.
- the translations T2 and T2' substantially determine the release of the attachment elements 24 and 24' and the return of the object-holder containers 12 and 13 to the situation of fig. 4b , so in this situation the object-holder containers 12 and 13 are again released.
- the attachment elements 24 and 24' are in fact again in correspondence with the grooves 34 and 34' made on the bars 15 and 16. Continuing in the extraction in direction L2, one passes from the situation of fig. 4b to the situation of fig. 4a .
- connection device 22 or 22' for example imagining that the attachment element 24 or 24' is automatically activated at entrance in order to sit astride both the bars 15 and 16 of the object-holder containers 12 and 13, determining the connection thereof and possibly de-activating automatically at exit, allowing the separation thereof.
- the automatic activation of the connection device 22 or 22' will be determined, for example, by the cam profile 32 or 33 and its possible automatic de-activation will be determined by the cam profile 32' or 33'.
- connection device 22 and/or 22' is provided with means which allow its automatic activation, in order to connect the object-holder containers 12 and 13 at the moment of insertion into the chamber 11 and to be able to extract them together once inside the chamber 11.
- the de-activation of the reciprocal connection of the object-holder containers 12 and 13 can preferably take place automatically and in correspondence with the entrance or exit aperture 17 of the treatment chamber 11, so that the first of the object-holder containers inserted, that is, the object-holder container 12 located furthest down the chamber 11, is, at the moment of separation from the second object-holder container 13, in proximity to the entrance aperture 17 of the chamber 11. This separation could however also take place manually, after the extraction of the object-holder containers 12 and 13.
- connection devices 22 and/or 22' and hence the reciprocal connection of the object-holder containers 12 and 13, for example the cam profiles 32 and 33, could also be disposed in more internal positions along the lateral walls 30 and 31 of the treatment chamber 11, provided, substantially, they are within a distance smaller than the travel of the object-holder containers 12 and 13 in the treatment chamber 11.
- the object-holder containers 12 and 13 do not need to be reciprocally joined, the reciprocal connection between them is necessary in the extraction step, when pulling the outermost object-holder container it must also be possible to pull out the innermost container.
- the present treatment machine 10 is therefore equipped with one or more connection devices 22 and 22' and with activation and possible de-activation means, that is, for example the cam profiles 32, 32', 33, 33', of an essentially mechanical type, therefore able to operate even in onerous and difficult operating conditions, such as those of a sterilization machine where the operating temperatures can also be quite high, even up to 140°C and where, therefore, it is inadvisable to use motorized and/or electric or electronic means for the reciprocal and automatic connection of the object-holder containers inside the chamber.
- activation and possible de-activation means that is, for example the cam profiles 32, 32', 33, 33', of an essentially mechanical type, therefore able to operate even in onerous and difficult operating conditions, such as those of a sterilization machine where the operating temperatures can also be quite high, even up to 140°C and where, therefore, it is inadvisable to use motorized and/or electric or electronic means for the reciprocal and automatic connection of the object-holder containers inside the chamber.
- the object-holder containers 12 and 13 can be disposed outside the chamber on a rollerway or other guide and support system to be inserted into and removed from the chamber 11.
- the rollerway or other guide system could be mobile with respect to the treatment chamber 11, so as to be able to be displaced for example, in order to move the object-holder containers 12 and 13 located on the rollerway to a zone different from that in which the treatment chamber 11 is located.
